Abstract
A sensor includes an elastic base material including a first surface and a second surface, a first sensor which detects a change in a capacitance caused by expansion/contraction of the first surface, and a second sensor which detects a change in a capacitance caused by expansion/contraction of the second surface. The first sensor faces the second sensor with the base material therebetween.
